We don’t want to create cost accounting vouchers for some transactions/generate any GL entries.  We are just trying to get the project into completed status.  

Normally I am able to temporarily change the ‘create cost accounting’ setting to ‘No’ on the relevant report code to ‘No, Do not update project cost’ via the option called ‘Update Cost Accounting’ in project transactions screen.

Example:

 Report Code SERVICES is set to 'No Do not update project Cost'.

However, when trying to update cost accounting, system prompts an error.

Any idea why this error prompts all of a sudden?
